There are four times as many brown skirts as black skirts in a sale. If there are 160 brown and black skirts altogether,
- how many brown skirts are there?
- how many more brown skirts than black skirts?
(a)
Number of black skirts = 1 u
Number of brown skirts
= 4 x 1 u
= 4 u
Total number of skirts
= 4 u + 1 u
= 5 u
5 u = 160
1 u = 160 ÷ 5 = 32
Number of brown skirts
= 4 u
= 4 x 32
= 128
(b)
Number of more brown skirts than black skirts
= 4 u - 1 u
= 3 u
= 3 x 32
= 96
Answer(s): (a) 128; (b) 96
